WattClarity® began in 2007.
Since that time there have been hundreds of articles posted, and increasingly we’ve found ourselves posting articles specifically focused on assisting with different aspects of energy literacy (at least in part because of the challenges this represents in our energy transition). In the table below, we’ve started collating some of these explanations, for easier future reference:
|(Generators) Avoiding Negative Prices||Based on increased interest from a range of generators (both Scheduled/Semi-Scheduled and also Non-Scheduled) in avoiding periods where trading prices are negative, we’ve put this focused page together.|
|Bidding and Dispatch Process||This page provides an explanation, and links to other resources progressively developed on WattClarity over the years.|
|Connection Point Dispatch (CPD) Price||Here’s a page explaining the Connection Point Dispatch (CPD) Price used in ez2view, and in the Generator Statistical Digest 2019|
|Credible Contingency||What AEMO means by “Credible Contingency” – and, by extension, a “Non-Credible Contingency” was explained here by Allan O’Neil in the context of the bushfires of summer 2019-20.|
|Cumulative Price||The Cumulative Price, and the Cumulative Price Threshold (and what this means for Administered Pricing) are all explained here.|
|Demand||This page provides an index to explanations on WattClarity.|
|Demand Response||“Demand Response” is a term used to a range of activities undertaken by electricity users to temporarily curtail consumption (or effectively lower net consumption from the grid through use of onsite generation) in response to some form of commercial incentive.
Given our keen interest in assisting with demand response at large energy users we established this focused site to help readers understand more about the different ways in which it might work.
|Dispatch Error||Introduce here.|
(Dispatchable Reserve Plant Margin)
|In the creation of our Generator Report Card (released 31st May 2019) we included analysis of a Dispatchable Reserve Margin, which was modelled on the IRPM that had been in use for many years,|
|AEMO terminology for Dispatchable Unit Identifier, the atomic level at which the NEM is dispatched.
Historically a DUID mapped most often to a discrete physical unit, but this was not always the case. With the the introduction of Semi-Scheduled Wind and Solar plant, the whole station will typically be registered as a single DUID.
|Fast Start||Here’s a page explaining the Fast Start Inflexibility Parameters (FSIP) which NEMDE takes account of in dispatch|
|Forecasts||We’re progressively fleshing out a page here to explain the various different types of forecasts provided by the AEMO under the NEM Rules.|
(Instantaneous Reserve Plant Margin)
|The Instantaneous Reserve Plant Margin is explained here.|
|Low Reserve Condition||The AEMO uses a three-level warning system alerting the market to actual, or forecast, periods of Low Reserve Condition – LOR1, LOR2 and LOR3.
This is described further here.
|Market Price Cap||The Market Price Cap sets the maximum level the dispatch price can reach through the dispatch process. It has been adjusted over time.|
|Market Price Floor||The Market Price Floor sets the lowest level the dispatch price can reach through the dispatch process.|
|Off-Target||In the creation of our Generator Report Card (released 31st May 2019) we included analysis of a the extent to which individual generators might be Off-Target.
The way this is calculated is discussed here.
|Price Energy Harvest||Here’s a page explaining the concept of ‘Price Energy Harvest’ used in ez2view|
|Price Setter||The price setting process is quite complicated – on WattClarity there are several articles published to help explain. These are all linked together here.
In Part 3 of our Generator Report Card (released 31st May 2019) we a view of how often a particular DUID has been heavily involved in setting the price in a given region.
